PLIERS.

Specification of Letters Patent.

Application filed March 15, 1920. Serial No. 365,902.

To all whom it may concern:

Be it known that I, ARTHUR EARNHART, a citizen of the United States,residin at Pondcreek, in the county of Grant and tate of Oklahoma, haveinvented new and useful in Pliers, of which the followmg is aspecification.

This invention relates to tools, particularly to pliers, and has for itsobject the provision of pliers having jaws formed con caved and serratedwhereby to facilitate gripping the heads of bolts or nuts, the jawsbeing further provided at one side with flanges extending their fulllength and extending beyond the concavities whereby to engage againstthe face-of a nut or bolt head to prevent the pliers from slipping downor beyond the nut or bolt head.

An important object is the provision of pliers of this character whichwill be simple and inexpensive in manufacture, highly efficient in use,durable in service, and a general improvement in the art.

With the above and. other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings inwhich Figure 1 is a side elevation of pliers constructed in accordancewith my invention, Fig. 2 is an elevation at right angles to Fig. 1, and

Fig. 3-is across sectional view through the jaws.

Referring more particularly to the drawings, the numerals 10 and 11designate members arranged in crossed relation and pivoted, asshown at12. At one end these members 10 and 11 are formed to provide handles,one of which is preferably formed as a screw-driver, as shown at 13. Theother ends of the members 10 and 11 constitute jaws and the jaws areformed on their confronting faces with concavities l4 and are serratedor toothed, as shown at 15. At one edge the jaws are formed with flanges16 which extend beyond the concavities and which are adapted to engage abolt head or nutgripped by the jaws, the purpose of the flanges being toprevent the jaws from slipping along the bolt head or nut, as will beapparent.

From the foregoing description and a study of the drawings it will beapparent that I have thus provided a very simple and inexpensive pllerswhich will be very efficient in gripplng action and which are partlyadapted for use in holding the head of a bolt while. the nut is beingunscrewed therefrom by a different tool.

While'I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit of the invention.

or the scope of the subjoined claim.

Having thus described my invention, I claim:

Pliers comprising a pair offmembers arranged in crossed relation andpivotally connected, said members being formed at one end to definehandles and having their other ends constituting jaws, the confront--ing faces of said jaws being concaved and formed with serrations, andflanges formed on and extending the full length of sald jaws at one sidethereof and projecting beyond theconcavities.

In testimony whereof I aflix my signature. ARTHUR EARNHART.
